摘　　要：目的评价肌电生物反馈(EMG-BFB)治疗技术对早期脑卒中偏瘫患者下肢运动功能改善的效果。方法将满足入选标准的78例脑卒中偏瘫患者随机分为EMG-BFB治疗组(42例)和对照组(36例)。治疗组在常规康复治疗基础上加用EMG-BFB治疗,1次/d,每周5次,连续治疗6周,共计30次。经专人对所有患者治疗前后肌电信号、肌力、踝背屈角度以及下肢运动功能(Fugl-Meye r量表)进行评定。结果 EMG-BFB组在踝背屈角度和下肢Fugl Meyer量表评分均优于对照组(P<0.05)。结论 EMG-BFB治疗对改善脑卒中患者偏瘫下肢运动功能较单独使用常规康复治疗效果更好。Objective To evaluate the effect of etectromyogram-triggered neuromuscular stimulating biofeedback （EMG-BFB） in improving lower extremity motor activity after stroke. Methods Seventy-eight subjects with stroke less than 4 weeks were randomly recruited to EMG-BFB （n=42） or control （n=36） group. All the subjects had a detectable EMG signal（〉 10 uV） by the surface of the muscle tibialis anterior and were tested by MMSE. Muscle strength of lower extremity was above Grade Ⅱ . Subjects of EMG-BFB group received a 30 minute treatment per day of ankle dorsiflexion exercise with EMG-BFB, and all the subjects （including both groups） also received conventional physical therapy in the treatment course of rehabilitation. EMG amplitude, muscle strength of ankle dorsiflexion AROM and Fugl-Meyer assessment were measured before and after treatment course. Results Subjects treated with EMG-BFB treatment had a greater development in ankle dorsiflexion and Fugl-Meyer assessment scores with controls （P〈 0.05）. Conclusions These results indicate EMG-BFB can improve the lower extremity motor activity of hemiplegia after stroke better than the conventional physical therapy alone.
